Antiques

Jack and Jim were walking around the local market.

“Antiques! Get your antiques, here!”

Jack decided to check and found himself face-to-face with the local conman, Billy MacBilly.

“Hello there young men! Want to buy a first edition, premier, Pride and Prejudice manuscript!”

Jack peered of the cover and saw Pride and Prejudice written in neat handwriting.

“All for a bargain of £20!” cheered the man, plastering a wide grin on his face.

“Or if you’re not interested, take a look a this is Of Mice and Men manuscript!” , waving a browning stack of paper.

A crowd of people were at the store, waving some cash.

“Stop!” hollered Jack “These books are fake!”

Mr. MacBilly’s smile dropped, and the crowd became angered.

How did Jack know?
